Physikalische Grundlagen1) Physical principles 1)

Mechanische Arbeit und elektrische Arbeit sind äquivalent. Es gilt: 1 Nm = 1 Wsmechanical Work and electrical work are equivalent. The following applies: 1 Nm = 1 ws

Das Anheben bzw. Absenken einer Masse ist mit dem Einsatz bzw. dem Gewinn von Energie verbunden. Wird die Masse von 1 kg an der Erdoberfläche um 1 m angehoben, so ist eine Arbeit von 9,81 Nm = 9,81 Ws zu verrichten.The Raising or lowering a mass is with the bet or the profit connected by energy. If the mass of 1 kg at the surface of the earth becomes 1 m, a work of 9.81 Nm = 9.81 Ws is to be done.

Die aufgewendete Arbeit zum Anheben des Körpers ist eine potentielle Energie, die beim Absenken des Körpers zurück gewonnen werden kann. Das Anheben eines Körpers kann damit zur Speicherung elektrischer Energie genutzt werden. In den nachfolgenden Beispielrechnungen wird vereinfachend das Anheben von 1 kg um 1 m mit 10 Ws angesetzt.The The work done to lift the body is a potential one Energy when lowering the body back can be won.

Stand der TechnikState of the art

Es ist bekannt, dass Pontons (z. B. Bootsstege, Landungsstege) gegen seitliches Verdriften durch Pfähle mit Gleiteinrichtungen fixiert2 ) werden. Die Pontons sind auf Schwimmkörpern angebracht, die bei Flut angehoben werden und bei Ebbe wieder absinken. Das Anheben der Schwimmkörper erzeugt potentielle Energie, die beim Absenken in Strom umgewandelt werden kann. Hat der Schwimmkörper eine ausreichende Wasserverdrängung, so kann auch ein Teil der Auftriebsarbeit in elektrische Energie umgewandelt werden.It is known that pontoons (eg, jetties, jetties) are fixed against lateral drifting by piles with slips 2 ) . The pontoons are mounted on floats, which are raised at high tide and sink again at low tide. Lifting the floats creates potential energy that can be converted into electricity when lowered. If the floating body has sufficient displacement of water, some of the buoyancy work can also be converted into electrical energy.

Zahnrad HubkraftwerkGear lifting power plant

Zeichnung 1 verdeutlicht die Funktionsweise eines Zahnrad Hubkraftwerks. Ein Schwimmkörper 1 (z. B. Ponton, Bootssteg, Schiff) wird bei Flut angehoben und bei Ebbe abgesenkt. Pfähle 5, an denen Zahnstangen 4 befestigt sind, fixieren den Schwimmkörper gegen seitliches verdriften. An der Zahnstange wird ein Führungswagen 2, der von dem Schwimmkörper über eine Verbindung 3 mit dem Gezeitenhub angehoben bzw. abgesenkt wird, entlang geführt.Drawing 1 illustrates the operation of a geared power plant. A float 1 (eg pontoon, boat dock, ship) is raised at high tide and lowered at low tide. piles 5 on which racks 4 Fixed, fix the float against lateral drift. At the rack is a carriage 2 which is connected by the floating body via a connection 3 is raised or lowered with the tidal stroke, led along.

Der Gezeitenhub leistet an dem Schwimmkörper eine Hubarbeit und erzeugt potentielle Energie. An dem Führungswagen ist ein Zahnrad 9 befestigt, das durch die Zahnstange 4 in Drehung versetzt wird. Das Zahnrad treibt über ein Getriebe 10 mit hoher Übersetzung einen Generator 11 an. Dieser speist den Strom in das Netz 6 ein.The tidal lift does a lifting job on the float and generates potential energy. On the carriage is a gear 9 fastened by the rack 4 is set in rotation. The gear drives via a gearbox 10 with high translation a generator 11 at. This feeds the electricity into the grid 6 one.

Zeichnung 2 skizziert die Aufsicht und Seitenansicht des Führungswagens 12 mit einer möglichen Anordnung der Führungsrollen und Antriebskomponenten 9, 10, 11. Die Zahnstange 4 ist kreuzförmig ausgebildet. Die Führungsrollen sorgen für einen festen Schluss zwischen Zahnstange und Zahnrad.Drawing 2 outlines the top view and side view of the carriage 12 with a possible arrangement of the guide rollers and drive components 9 . 10 . 11 , The rack 4 is formed cross-shaped. The guide rollers provide a tight fit between the rack and gear.

Zeichnung 3 skizziert ein Zahnrad Hubkraftwerk, bei dem der Schwimmkörper 1 über eine Verbindung 14 mit einer Kette 13 verbunden ist. Die Kette treibt über das Zahnrad 9 und das Getriebe 10 den Stromgenerator an.Drawing 3 outlines a gear lifting power plant, in which the float 1 over a connection 14 with a chain 13 connected is. The chain drives over the gear 9 and the gearbox 10 the power generator on.

Vergleichbare Hubeinrichtungen können auch mit Seilzügen und anderen mechanischen Vorrichtungen (z. B. Spindeln, Hebel) hergestellt werden.comparable Lifting devices can also with cables and other mechanical devices (eg, spindles, levers) become.

Folgende Vorteile eines Zahnrad-Hubkraftwerks können erreicht werden:
Zahnrad-Hubkraftwerke liefern grundlastfähigen Strom aus Erneuerbaren Energien.The following advantages of a geared lifting power plant can be achieved:
Cogwheel power plants supply base-loadable electricity from renewable energies.

Zahnrad-Hubkraftwerke können kostengünstig aus marktgängigen Komponenten hergestellt werden. Sie können leicht an bestehende Schwimmkörper (z. B. Ponton, Bootssteg, Schiff angebracht werden.Gear Hubkraftwerke can economical from marketable Components are manufactured. You can easily to existing floats (z. B. pontoon, boat dock, ship are attached.

Zahnrad-Hubkraftwerke liefern einen Zusatznutzen an bestehenden oder zukünftigen Pontonanlagen. Die Tragfähigkeit und damit das nutzbare Gewicht bestehender Pontonanlagen kann durch zusätzlich angebrachte Schwimmkörper erhöht werden.Gear Hubkraftwerke provide added value to existing or future ones Pontoons. The carrying capacity and thus the usable weight of existing pontoon plants can be through additionally attached floats elevated become.

Der Auftrieb der Schwimmkörper kann in dem Maße genutzt werden, mit dem das Volumen der Schwimmkörper die durch das Gewicht verdrängte Wassermenge übersteigt.Of the Buoyancy of the floats can to that extent be used, with which the volume of the floating body by the weight displaced amount of water exceeds.

Eine Beispielrechnung verdeutlicht die erzielbaren Potentiale:
Der Schwimmkörper, der z. B. einen Bootssteg trägt habe einen nutzbaren Querschnitt H × B von 3 m × 4 m. Je Meter Länge verdrängt der voll belastete Schwimmkörper 12 m3 das sind 12 t Wasser. Auf einer Länge von 30 m ergibt sich ein Gewicht der verdrängten Wassermenge von 360 t. Bei einem Gezeitenhub von 5 m wird der Schwimmkörper täglich um ca. 10 m angehoben. Die potentielle Energie dieses Stegsegments beträgt: ca. 360.000 kg × 10 m × 10 Ws/kg m = 36.000.000 Ws = 10.000 Wh = 10 kWh.A sample calculation illustrates the achievable potentials:
The float, the z. B. carries a jetty have a usable cross-section H × B of 3 m × 4 m. For each meter of length, the fully loaded floating body displaces 12 m 3, which is 12 t of water. Over a length of 30 m results in a weight of the displaced water amount of 360 t. With a tidal lift of 5 m, the float will be raised by approx. 10 m per day. The potential energy of this web segment is: approx. 360,000 kg × 10 m × 10 Ws / kg m = 36,000,000 Ws = 10,000 Wh = 10 kWh.

Die Stege eines Yachthafens seien 1.500 m lang. Unter der obigen Annahme können sie täglich ca. 500 kWh Strom erzeugen. Das sind ca. 180 MWh pro Jahr, ausreichend den Jahresstromverbrauch von ca. 60 Haushalten zu decken.The Jetties of a marina are 1,500 m long. Under the above assumption can daily approx. Generate 500 kWh of electricity. That is about 180 MWh per year, sufficient to cover the annual electricity consumption of about 60 households.
